 |
43fc5bca | 2015-08-03 23:34:05 | Correct powerpc sysv stack argument accounting ppc32 starts using the stack for integer arg passing when we run out of integer arg passing registers. Similarly, we start using the stack for floating point args when we run out of floating point registers. The decision on where an integer arg goes does not depend on number of floating point args, nor does the decision on where a floating point arg goes depend on number of integer args. Alignment of stack args also simply depends on number of stack args. This patch untangles the horrible mess we had, with intarg_count being wrongly used to count both integer args and stack words. * src/powerpc/ffi_sysv.c (ffi_prep_cif_sysv_core): Count fprs, gprs, and stack words separately. (ffi_prep_args_SYSV): Similarly. | |
 |
1f6b5a91 | 2015-07-26 16:27:34 | Support the WIN64/EFI64 calling convention on all X86_64 platforms Add a new calling convention FFI_EFI64, alias FFI_WIN64, on all X86_64 platforms. This allows libffi compiled on a 64-bit x86 platform to call EFI functions. Compile in ffiw64.c and win64.S on all X86_64 platforms. When compiled for a platform other than X86_WIN64, ffiw64.c suffixes its functions with _efi64, to avoid conflict with the platform's actual implementations of those functions. | |
|
6de51f3e | 2015-07-26 16:23:55 | src/x86/ffiw64.c: Don't assign a "char *" to an "unsigned char *" Declare a local variable to match the type of the struct field assigned to it, rather than adding unsigned to the type. Fixes a -Wpointer-sign warning. | |
|
eaa59755 | 2015-07-26 17:17:16 | src/x86/win64.S: Handle name mangling and PIC Move the macros from unix64.S into a shared header asmnames.h and use them in win64.S too. | |
|
c8e82d9f | 2015-07-26 16:18:57 | src/x86/win64.S: Support compiling on non-WIN64 platforms Non-WIN64 versions of the GNU assembler don't support the .seh_* directives for structured exception handling, so wrap them in a macro that compiles to nothing. Handle the registers used for the non-Windows x86-64 calling convention when on a non-Windows platform. Distinguish between cases that should refer to the native argument registers (defined as arg0, arg1, arg2, and arg3) and cases that should always refer to the Windows argument registers. | |
|
e3d2812c | 2015-04-25 19:03:03 | Modified arm/sysv.S to remove directives not allowed by clang. | |

d68c8aed | 2015-01-16 11:40:33 | sparc: Solaris fixes, part 2 /bin/as seems to only understand single-digit labels /bin/as knows nothing about .rept/.endr | |
 |
b740ab7c | 2015-01-16 11:32:23 | sparc: Solaris fixes * /bin/as requires .type fn,#function instead of @function. * /bin/as doesn't support .macro/.endm. I'm using preprocessor macros instead to implement E in src/sparc/v[89].S. | |
|
f1560b7b | 2015-01-16 11:31:37 | x86: Solaris fixes * Solaris/x86 /bin/as doesn't support .org, so I've just disabled the uses in src/x86/{sysv, unix64}.S, as on Darwin. * Solaris/x86 needs to use EH_FRAME_FLAGS so manually and compiler generated .eh_frame sections match, otherwise libffi.so fails to link: * Solaris/x86 /bin/as has different COMDAT syntax; I've disabled it for the moment. | |

53636634 | 2015-01-16 15:19:38 | aarch64: implement the trampoline table workaround for ffi closures on Apple systems This is a direct copy/paste port of the ARM code, with changes because of Aarch64 pc-relative addressing restrictions. | |
|
05e65b4e | 2015-01-16 15:18:04 | aarch64: rewrite range syntax into list to appease Clang Clang's assembler in Xcode 6 appears to choke when the operand of st4 is a range, but is happy with a list. | |
|
f27c4e46 | 2015-01-13 07:22:07 | x86: Fix thinko in ffi_raw_call Missed structure initialization for raw path. Apparently there are no tests for this outside gcc. | |

|
6cedf81c | 2014-12-10 09:43:58 | x86: Expand FFI_GO_CLOSURE If we're going to have to hand-write unwind info for darwin, these macros make the job harder. | |
 |
ae842a51 | 2014-11-25 11:43:40 | x86: More Darwin unwind fixups EHFrame{N} IIRC is a special cue to ld64 that it should treat the unwind in the object as "special/legacy" .. [these days everything is .cfi_xxxx (except, cctools-as, as you noted)] .. without that much confusion arises with ld64's atom-isation of the eh_frame section. xxxx.eh labels are not needed for darwin ld64 >= 85.2.1 (i.e. darwin9, xcode 3.1.4) to all intents and purposes, that's all that matters now, since I think that anyone trying to build on 10.4/darwin8/xcode2.5 would have to use a later ld64 (from odcctools) for other reasons. | |
|
8fa3c9f2 | 2014-11-25 09:27:54 | x86: Reinstate hand-written unwind info for unix64.S One more try to get default Darwin to work. | |
|
5f35e0ff | 2014-11-24 16:26:50 | x86: Avoid using gas local labels Which are unsupported by Darwin cctools as. Thankfully this doesn't uglify the source too much. | |
|
ed1ca277 | 2014-11-24 13:02:03 | x86: Remove use of .cfi_escape The unwind info isn't 100% correct at all points during the epilogue, and not annotating is just as incorrect as the annotation. This works better on systems that do not support DW_OP_call_frame_cfa. | |
|
1b12593d | 2014-11-24 12:55:43 | x86: Honor alignment of arguments Darwin aligns long-double to 16, and thus all of the long double tests were failing due to not honoring that. We ought to be able to devise a test case for GCC using __attribute__((aligned)) that would have failed too. | |
|
042b8daf | 2014-11-24 11:24:02 | x86: Use .balign not .align The Apple assembler defaults to power of two alignment, rather than byte alignment like everyone else. Force byte alignment by using the proper directive. | |

7ba30b19 | 2014-12-19 11:38:17 | s390: Inline and tidy ffi_prep_args As per discussion with Ulrich Weigand, document the restrictions on the code within ffi_call_int as we simultaneously prepare stack frames for ffi_call_SYSV and the target function. | |
|
f69ec6f3 | 2014-12-18 16:21:07 | s390: Use pc-relative insns in 31-bit mode It's silly to stick to esa/390 features when the compiler won't. Detect when brasl and larl are used by the compiler and then use them in the assembly. | |
|
2f530de1 | 2014-12-18 16:01:59 | s390: Reorganize assembly Avoid using ffi_prep_args as a callback; do all the work setting up the frame within ffi_call_int directly. Save fewer registers in ffi_closure_SYSV. | |

2f652469 | 2014-12-11 14:16:00 | x86: Handle void arguments as if an empty structure Since libffi currently doesn't allow empty structures, libgo currently maps them to ffi_type_void. Given that we'll abort on this case, handle it gracefully. | |

590663b3 | 2014-11-18 12:56:58 | powerpc: Fix ffi_go_closure_linux64 Unlike ffi_closure_LINUX64, this entry point is called normally, so we already have the TOC in R2 and the closure in R11. * powerpc/linux64_closure.S (ffi_closure_LINUX64): Remove a register dependency chain.

542e0047 | 2014-11-18 05:07:00 | sparc: Define FFI_TARGET_SPECIFIC_VARIADIC for v9 This is a port of http://gcc.gnu.org/viewcvs?rev=207763&root=gcc&view=rev aka GCC PR libffi/60073, to the rewritten Sparc codebase. Supposedly, we should have seen failures with the existing libffi.call/cls_double_va.c testcase, but I hadn't. Perhaps a gcc newer than 4.6.3 is required to see that... | |

6eec410f | 2014-10-26 15:29:04 | sparc: Re-add abi compliant structure support The original code, removed in the "rewrite" patch, was incorrect for large structures, and required dynamic allocation of a trampoline on every ffi_call. Instead, allocate a 4k entry table of all possible structure returns. The table is 80k, but is read-only and dynamically paged, which ought to be better than allocating the trampoline. This is difficult to test with gcc. One can only use -O0 at present. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63668. | |

2b27890b | 2014-10-24 16:10:48 | sparc: Rewrite everything It's impossible to call between v8 and v9 ABIs, because of the stack bias in the v9 ABI. So let's not pretend it's just not implemented yet. Split the v9 code out to a separate file. The register windows prevent ffi_call from setting up the entire stack frame the assembly, but we needn't make an indirect call back to prep_args. | |
